Comparative Analysis of Impact of Biofertilizers on the Yield of Solanum tuberosum

Potatoes (Solanum tuberosum) play a crucial role in global food security and nutrition, particularly in India where they are a staple crop. However, the excessive use of chemical fertilizers in potato cultivation has led to environmental degradation and economic challenges. This study investigates the potential of biofertilizers as eco-friendly alternatives to chemical fertilizers in enhancing potato yield. A comparative analysis was conducted to evaluate the impact of biofertilizers containing nitrogen-fixing, phosphorus-solubilizing, and potassium-mobilizing bacteria on potato growth and soil health. Field trials were conducted using a randomized complete block design, with various biofertilizer treatments applied to potato crops. Results indicated that biofertilizer-treated plants exhibited higher yields, improved growth parameters, and enhanced soil health compared to those treated with chemical fertilizers or left untreated. Statistical analysis confirmed significant differences in yield and growth parameters among treatment groups, highlighting the efficacy of biofertilizers in promoting sustainable agriculture. These findings emphasize the potential of biofertilizers to improve crop yield, soil health, and environmental sustainability in potato cultivation. Further research exploring optimal formulations and application methods is recommended to maximize the benefits of biofertilizers in agricultural systems.
